摘要： A device may verify whether pinholes in a perimeter protection device are open and may determine pinhole opening and closing delays. The method for determining the pinhole opening delay may include sending a stream of packets for passing through the pinhole in the network perimeter protection device. The packets in the stream may be sent at known time intervals. The method may include receiving one or more of the packets in the stream, wherein the received packets passed through the pinhole. The pinhole opening delay may be based on an indication of the position of the first one of the packets received in the stream and the known time intervals. The pinhole closing delay may be based on the number of packets having passed through the pinhole, after sending a session termination message, and the known time intervals.

摘要： A method of processing a call request to a callee in a network telephony system is provided which includes mapping a hostname portion of a callee address to a canonical form of the hostname and determining a canonical form of a username portion of a callee address. The canonical form of the user identity of the callee is then used as an index to a user database to retrieve a callee database record. The callee database record is then used to determine call routing based on the retrieved callee database record, such as user location, preferences and policy data stored in the record. The method is generally performed by a signaling server in the network, such as a SIP proxy server. The signaling server can also provide security features such as caller authentication. A scalable signaling and routing architecture is also provided.

摘要： A conferencing server is provided for a data network telephony system for facilitating multi-party call conferencing. The conferencing server generally includes a session initiation protocol (SIP) signaling interface and a media conferencing module. The media conferencing module includes a number of selectable media decoders compliant with known media CODEC protocols, such as G.711. A number of media stream queues s are selectively coupled to the media decoders for storing the decoded incoming media streams. A jitter correction processor is provided to compensate for arrival time jitter in the data stored in the media stream queues. A mixer, which receives the jitter corrected data from each of the queues, generates an aggregate conferencing stream of all active participants and generates individual participant conference streams for each active participant in the conference. A number of selectable media encoders are then used to encode the individual participant conference streams in accordance with a media CODEC protocol supported by the respective participant. The encoded participant conference streams are then distributed to the various conference participants via the data network, such as the Internet.

摘要： A method for generating a rich persistent conversation history from structured and unstructured information using a communication protocol is provided. The method includes (i) receiving media contents associated with conversations from messaging channels, (ii) selecting a set of selected messaging channels from where the media contents are received, (iii) demarcating boundaries in each of the media contents associated with the conversations based on an activity of users, (iv) inserting segmentation demarcations to a first conversation to differentiate the first conversation from a second conversation, (v) determining communication elements for each conversation associated with the segmentation demarcations on each messaging channel, (vi) generating a conversation snippet by linking the communication elements for each messaging channel, (vii) linking conversation snippets to generate a segment associated with the conversation for each messaging channel using lexical and non-lexical features and (viii) generating the rich persistent conversation history by linking segments from the messaging channels.

摘要： A mobile node includes a processor, a network interface, and a storage device having computer program code for execution by the processor. The computer program code includes a network layer for transmitting and receiving packets and an intermediate driver that transmits packets to the network layer and receives packets from the network layer using a virtual internet protocol (IP) address to identify the mobile node. The intermediate driver transmits packets to the network interface and receives packets from the network interface using a routable actual IP address to identify the mobile node. The intermediate driver permits the actual IP address to change when the mobile node moves from a first subnet to a second subnet without a corresponding change in the virtual IP address. A corresponding NAT associates the virtual IP address with a second actual IP address when the NAT is notified that the mobile node is in the second subnet.

摘要： Embodiments of the present disclosure include systems and methods of handling ink using a movable spittoon platform. A frame defines at least a reservoir portion and a side wall protrusion adjacent the reservoir portion. A shuttle includes a platform slidably movable between a first position, in which the platform is biased to extend outwardly from an end portion of the shuttle, and a second position, in which the platform becomes retracted relative to the end portion of the shuttle. The shuttle is slidably movable relative to the frame toward the spittoon portion wherein, upon releasable contact of the platform against the protrusion, the platform moves from the first portion into the second portion to scrape ink off the platform into the reservoir portion below the shuttle.
